摘　　要：[目的]阐明多氟苯甲酰脲TXH09对柑橘潜叶蛾的田间防效和保梢效果。[方法]采用叶面喷雾法。[结果]5%TXH09水分散颗粒剂和5%TXH09乳油可有效地控制柑橘潜叶蛾的为害,具有较好的速效性和持效性,对柑橘具有很好的保梢作用。5%TXH09 WG的害虫防效和保梢效果均与5%氟铃脲EC无显著差异。5%TXH09 EC的幼虫防效优于5%氟铃脲EC,但保梢效果稍弱。较高的气温有助于提高TXH09的害虫防效和保梢效果。[结论]TXH09是防治柑橘潜叶蛾的高效杀虫剂。[Aims] This study aims to clarify the field efficacy of difluorobenzoyl urea compound TXH09 in controlling citrus leaf miner（Phyllocnistis ctrella） and its effect on citrus preservation. [Methods] Foliar spray method was used.[Results] TXH09 5% WG and TXH09 5% EC showed an effective and persistent effect in decreasing the numbers of the miner larvae accompanying with good preservation for citrus shoots. TXH09 WG revealed good effect on pest control and preservation that were similar to those of hexaflumuron 5% EC. TXH09 EC had better pest controlling effect but slightly lower shoot-preservation effect than hexaflumuron EC. Moreover, higher temperature is benefit for TXH09 to control the miner larvae and to preserve citrus shoot. [Conclusions] TXH09 is a potential agent used effectively against citrus leaf miner.
